An object accelerating at constant acceleration (a) has an initial velocity v0 (at t=0), a velocity v at time t, and goes a particular distance d or x - x0 during the time interval. Derive the expression relating v0, v, a, and d (or x-x0). The relation must not include time. You may use either algebra or calculus.
As a training exercise, a soccer player must run the length of the soccer field (leg 1), then turn around and run back to her starting point (leg 2) without stopping. If the length of the soccer field is L meters, and she runs the leg 1 in t 1 seconds, then turns around and runs leg 2 in t_2 seconds, find the following: (Write your answers using the symbols as they are written in the question.) a) Her average velocity during leg 1 was L/t'1 m-s 1, b) Her average velocity during leg 2 was L/t 2 m-s1. c) Her average velocity over the entire exercise was m-s 1. d) Her average speed during the entire exercise was 2L/t_1+t_2 m-s1.

Traffic shock wave. An abrupt slowdown in concentrated traffic can travel as a pulse, termed a shock wave, along the line of cars, either downstream (in the traffic direction) or upstream, or it can be stationary. The figure shows a uniformly spaced line of cars moving at speed v = 27.0 m/s toward a uniformly spaced line of slow cars moving at speed vs = 5.30 m/s. Assume that each faster car adds length L = 13.0 m (car length plus buffer zone) to the line of slow cars when it joins the line, and assume it slows abruptly at the last instant. (a) For what separation distance d between the faster cars does the shock wave remain stationary? If the separation is twice that amount, what are the (b) speed and (c) direction (upstream or downstream) of the shock wave?
The graph shows the displacement-time history for the rectilinear motion of a particle during an 8-second interval.

Assume you are driving a car at a constant speed of 76 km/h. Suddenly you see a deer standing on the highway and you must put on the brakes. Your reaction time (time elapsed between the moment you see the deer and your foot hitting the brakes) is 0.118 s. The brakes provide an acceleration with a magnitude of 4 m/s2, and a direction opposite the initial velocity. How do you find the total distance traveled?
UST Eco-Tiger vehicle climbed to a hill which is defined by the equation, x2 =625(16 -y). If the vehicle moves from point A with a speed of 20 m/s and startsto speed up at constant rate for exactly 4.72136 seconds until it reachespoint B. Determine the magnitude of the vehicle's acceleration when thedistance from A and B is 100 meters.
The velocity (in m/s) of a particle is given by v(t) = 2t- 6 where t is the time in seconds. During the interval 0
Complete solution and answer must be simplified. A particle is moving on a straight line has acceleration a=5-3t and it's velocity is 8 at time=2. If s(t) is the distance from the origin, find s(2) -s(1). Note : s (t) = f v dt v (t) = f a dt
A particle moves in a straight line with uniformly accelerated motion. From the initial point, the particle covers a distance of 4 m in 1 s, and a distance of 18 m in 3 s. Find (a) the initial specd and the acceleration of the particle, (b) the speed of the particle after 5 s, (c) the speed of the particle when it is 10 m away from its initial point.
The position of a particle in millimeters is given by s = 112 - 23t+t² where t is in seconds. Plot the s-t and v-t relationships for the first 16 seconds. Determine the net displacement As during that interval and the total distance D traveled. By inspection of the s-t relationship, what conclusion can you reach regarding the acceleration?
The motion of a particle is defined by the relation x= t2-(t -2)3, where x and t are expressed in feet and seconds, respectively. Determine (a) the two positions at which the velocity is zero (b) the total distance traveled by the particle from t = 0 to t = 4 s.
A special racing car starts from rest and accelerates in a straight line with a constant acceleration of 5.8 m/s². After 376 metres, it deploys a parachute which results in a deceleration of kv? where v is the speed of the car in m/s and k is a constant (has a unit of 1/m). If the car's speed slowed down to 37 km/hr 7.5 seconds after the parachute was deployed, determine the constant k and then give your answer to Z = 1000*|k| rounded to two decimal places. Note that |k| means the absolute value of k.
